6)  The arrow on the vent cap should 

be pointing up. Insure that the 1-1/2" 
clearances to combustible materials 
are maintained (Diagram 4). Install the 
termination cap.

If the Snorkel Termination must be installed 
below grade, i.e. basement application, proper 
drainage must be provided to prevent water 
from entering the Snorkel Termination. Refer 
to Diagram 4. Do not attempt to enclose the 
Snorkel within the wall, or any other type of 
enclosure.

1)  Set the unit in its desired location. Check 

to determine if wall studs or roof rafters 
are in the way when the venting system is 
attached. If this is the case, you may want 
to adjust the location of the unit. Rough in 
the gas preferably on the right side of the 
unit and the electrical (junction block is on 
the left side) on the left.

2)  Direct Vent pipe and fi ttings are designed with 

special twist-lock connections to connect the 
venting system to the appliance fl ue outlet. A 
twist-lock appliance adaptor is an available 
option that must be used in conjunction with 
the Simpson Dura-Vent Direct Vent GS 
system. 

3)  Put a bead of silicone inside the outer section 

of the adapter and a bead of Mill Pac on 
the inner collar. Slip the adapter over the 
existing inner and outer fl ue collar and fasten 
to the outer collar only with the 3 supplied 
screws (drilling pilot holes will make this 
easier). Level the fi replace and fasten it to 
the framing using nails or screws through 
the nailing strips.

4)  Assemble the desired combination of pipe 

and elbows to the appliance adaptor and 
twist-lock for a solid connection.

Note:
 a) 

 

Twist-lock 

procedure: 

Four 

indentations, 

located on  the female ends of pipes and 
fi ttings, are designed to  slide straight 
onto the male ends of adjacent pipes 
and fi ttings, by orienting the four pipe 
indentations so they match and slide 
in to the four entry slots on the male 
ends, Diagram 1. Push the pipe sections 
completely  together, then twist-lock 
one section clockwise approximately 
one-quarter turn, until the two sections 
are fully locked. The female locking lugs 
will not be visible from the outside, on 
the Black Pipe or fi ttings. They may be 
located by examining the inside of the 
female ends.   

 b)  Horizontal runs of vent must be 

supported every three feet. Wall straps 
are available for this  purpose.

5)  Mark the wall for a 10" x 10"  square hole. 

The center of the square hole should line 
up with the centerline of the horizontal pipe. 
Cut and frame the 10 inch square hole in 
the exterior wall where the vent will be 
terminated. If the wall being penetrated is 
constructed of non-combustible material, 
i.e. masonry block or concrete, a 7"(178mm) 
dia. (7-1/2"(191mm) dia. for fl ex) hole is 
acceptable.

Note:
 a)  The horizontal run of vent must be level, 

or have a 1/4 inch rise for every 1 foot 
of run towards the termination. Never 
allow the vent to run downward. This 
could cause high temperatures and may 
present the possibility of a fi re.

 

b)  The location of the horizontal vent termi-

nation on an exterior wall must meet all 
local and national building codes, and 
must not be blocked or obstructed.  For 
External Vent Terminal Locations, see 
diagram in the "Exterior Vent Termination 
Locations" section.

 

c)  Snorkel Terminations:

 

 

For installations requiring a vertical 
rise on the exterior of the building, 14-
inch and 36-inch tall 
Snorkel Terminations  
are available, as 
well as the standard 
Riser Vent. Follow the 
same installation 
procedures 
as used for
